OE WINNSBORO, TEXAS;

FLEXIBLE-ARMOR Foe HOSE ANDPlPlNG.

To all whom it may concern: Be it known that I, WELBY DUNBAR WEIR, a citizen of the United. States, residing at Winnsboro, in the; county of Woods and State of Texas, have invented a newand useful Flexible Armor for Hose and Piping, of which the following is a specification, Q

This invention relates to flexible armor for hose, pipes, tubingjand the like, and has for ID its object to provide an inexpensive, durable, and eflicient armor of'this character pos sessing the requisite degree of flexibility to permit the hose to be easily coiled and used under ordinary conditions.

1 5 'A further object of the invention is to provide an, armor formed of a plurality of overlapping members which surround the hose or pipe and form, in effect, a contihuous protectmg casing or eovering for the same, thereby 2o preventing the hose from kinking and ren dering the same capable ofwithstanding enormous internal and external pressure.

A still further object is to provide means for maintaining the overla ping members in 2 5 'yieldable contact with eac other. i With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the 5 principle or sacrificing any of the advantages of this invention. 1

In the accompanying drawings, forming a part of this specification, Figure 1 1s a side- 5 armor exposed. Fig. 4 is a 101i itudinal sec tional view illustrating a fort er modified form of the invention; and Figs. 5 to 19, in-

. elusive, are similar views illustrating further -modified forms of the invention.

5o Similar numerals of reference indicatelcorrespondin'gparts in all g the figures of the drawings. i

In'the preferred form of the device illustrated in Fig. lot the drawings, 5 designates 5 5 a section of hose of the ordinary form and I Specification of Letters Patent. Attumiti'fiiea August 21,1905. Serial No. 275,157.

construction. to one end of which is secured in any suitable manner, as by clamping-bands 6 and 7, a coupling member 8 for attachment I to a hydrant or to a similar hose-section.

Surrounding the exterior walls of the hose 6o 5 are a plurality of telescopic rings or mem- "bers 9, which may be cast, 5 un, stamped, or otherwise formed from thin s eet metal-such as steel, brass, aluminium,.or other suitable material-said rings being preferably in the form of hollow truncated cones, as shown; and having their enlarged ends bent or'--- curved laterally to .form annulai'strengthen ing ribs or beads 10. The rings 9 are refer ably, arranged on the hose 5 with tlie en: larged upper end of one ring overlap ing-the reduced or contracted lower end of t .e adjacent ring, thereby forming an inner protecti ing'covering or armor for the hose, which possesses the requisite degree of flexibility to 7 5- permit the latter to be easily coiled and used under ordinary conditions. Arranged con centric with the inner set of rings 9 is an outer set of rings 11, preferahlyof the same shape and construction as the rings 9,but 8o disposed in reverse order, as shown, while intcrposed between the two sets of rings is a 'flexihle separating tube or sheath 12.-

Surrounding the outer set of rings 11 is a flexible protectingcasing 13, the end of which bears against a shoulder H- on the coupling member 8 and is separated from the adjacent end of the tube or sheath 12 by a spacing member or block 15, a similar spacing member 16 serving to separate the tube 0 or sheath from the hose 5.

Arranged on each side of the spacing members or blocks 15 and 16 are metal tubes or' sleeves 17, and interposed between said sleeves are coil-springs 18, one end of each of 5 which bears against the adjacent block, while the opposite end thereof engages a slidingcollar 19. One of the" slidingv collars normally bears against the upper ring of the inner set of protecting members, while the ad'acent collar: too,

ears against the upper rin oft e outer set, thereby exerting a constant on itudinal pres v sure on the succeeding rings oi each set and maintaining said rings inconstant contact 13 with each other throughout the entire length :05 of the hose. Any number of coil-springs may be employed iorexcrting a lon itudinal pressure-onthe metal rings, and sai' springs instead of being positioned at one end of the hose may be placed at an intermediate point no other bya coll-spring 10, interposed between 45 ;-2,-are em loyed, thelatter being covered and of the rings are curve n to g .fesomse onthe latter and interposed-between any twol ing flange 35 at the bottom-of the ring. 65

of the rings of either or both sets of protecting members. a

The clamping-bands 6 and 7 preferably en- 5 age the outercasing 13, so that when said ands are ti htened the casing, hose, and intermediate sheathing will be securely clam ed to the reduced extension 20 of the coupling member. In Fig. 2 of the drawings there is illustrated a; modified form of the invention, in which the inner set of overlapping rings 9 forms a metal lining for the hose, this construction of hose being particularly desirable when the latter is designed for conducting water mixed with sand, powdered emery, or other forei n matter which has a tendency to cut and otierwise injure the hdse. In this Tease the reduced extension of the cou ling to member is provided with an annular s oul- -der 421 for enga ement'with the separatingsheath 22, the atterbeing held in contact with the extension by a spacing-sleevej23.

the coil-s rings 18 and are also provided with suita le recesses adapted to receive the metal sleeves or' tubes 17 the sliding'collars 19 being disposed within the recesses 24, ,as shown. 4

In Fig. 3 the hose 5 is secured directly to the c'buplin member -8 by the clampingbands 6 and 7, while the overlapping rings 9 are dis osed on the exterior walls of the hose and eld n yieldable contact with each the clamping member 6 anda sliding collar '12. The members 9 in this form pf the device are preferablv constructed with smooth exterior'wallsand are preferably galvanized or .otherwiseplated or coated, so as to prot et-the-sam when exposed to the action of the elements.

In Fig. 4 a single set or series of rotectingrings9, similar to those shown in igs. 1 and protecte by an outer casing or tube 25.

, In Fig. 5 the upper and lower edges of the I metal ring are curved or bent inwardly, as I;

indicated at 26, while in- Fig. 6 the upper edge 27 is curved outwardly and the lower ed e 28 bent inwardly, as shown. n Fig; 7- both the up er and lower edges aterally against the exterior Walls, as indicated .at 29 and 30, respectively,-and in Fig. 8 the reduced end of t s ring is bent inwardly at 31 against the interior Walls of said ring.

In 9 the reduced end of the ring is provided with an inwardly-projecting flange 32, a similar flange 33 being shown at both the upper and the lower edge of the ring (illustr ted inFig. 10) andanoutwardly-extending fi ings 34 at the top, and aninwardly-extend- The spacing-sleeve zfndiextension are formed with annular'recesses 24 for the reception of (Shown in Fig. 11.)

In Fig. 12 the metal ring is provided with' a single laterally-curved flange 36, located at the top of the ring, while in Fig. 13 both the upper and lower edges of the ring are curved laterally, as indicated. at 37.

5 In Figs. 14 to 19, lnclusive, the overlaplng protecting members forming the lienle armor are arranged to interlock with each.

other, as shown, said members being slightly different in shape from the members shown in Figs. 1 and 2 of the drawings, but serving tojperform the same function-namely, to form a metallic casing or covering for the hose.

In Fig. 14 the side walls of the protecting members are in the form of a compound or ogee curve, the opposite ends thereof being curved laterally in opposite directions to form annular beads or flanges 26, adapted to engage the corresponding annular beads or flanges of adjacent members.

In Fig. 15 the enlarged end of each protecting member is bent to produce an inwardly-extending annular bead 27 which engages an annular groove 28 in the reduced end of the adjacent member.

In Fig. 16 the reduced end of each member is provided with an annular head 29 for engagement with the inwardly-extending lip 30' on the enlarged end ol the succeeding member, while in Figs. 17 and 18 the annularbeads are dispensed with, the flanged end of one member engaging the end of the adjacent member, as shown at 31.

In Fig. 19 I have shown the position assumed by the interlocking protecting members when the hose is bent'or coiled, it being understood thatall of theinterlocking members shown in the drawings will in practice be spaced a sullicient distance from the hose and from each other to permit the requisite freedom of movement of said members in manipulating the hose.

The several forms of the device above described may be used with or without a prbtecting sheath or covering, and the coil spring or springs for maintaining said members in contact may be employed or dlsp'ensed with, as desired.

The flexible armor, while capable of being I used whenever re uired, will e found particularly serviceab e in connection with hose for air-brakes, dredges, pneumatic hammers, drills, painting and spraying ap aratus, firehose, and in allhydraulic and pneumatic ap liances.
